Modeling computed radiography with imaging plates
Résumé
Computed Radiography is a potential replacement technology for
traditional film radiography, promising shorter exposure times and a wider exposure
range while maintaining the advantage of detector flexibility, which is relevant for
instance for panoramic exposures.
Computer modeling can play a supporting role in the handling of the transition
to a new inspection technique, facilitating the definition of the optimal operating
conditions. We present the result of a thesis carried out at INSA Lyon and supported
by Areva, EDF and GE, aiming to develop a computer model for the entire acquisition
chain from exposure to optical read-out of an imaging plate, as well as its actual
implementation in an industrial code, and an illustration of its application.
